Hydrologic Outlook
National Weather Service Seattle WA
345 PM PST Thu Dec 7 2023


...THREAT OF RIVER FLOODING WEDNESDAY NIGHT THROUGH FRIDAY FOR PARTS
OF CENTRAL AND SOUTHERN WESTERN WASHINGTON...


A frontal system will bring another round of widespread lowland rain
and mountain snow with snow levels rising to between 6000 and 6500
feet. Though considerably weaker than the last event earlier this
week, forecast rainfall totals have increased today and are from 2-3
inches in the Cascades and 3-4 inches  in the Olympics. Snow levels
are also forecast higher. Combined with recent heavy rains that has
rivers running high and soils already saturated with little time to
dry out, this will lead to significant rises on streams and rivers.
There is also a low chance of exceeding flood stage on river in the
outlook areas of King, Thurston, Grays Harbor, and Lewis Counties.

Please monitor the latest river forecasts from the National Weather
Service for additional information.
